Mobil 0w40 for my 7.3L ?

I have a 2020 F350 with a 7.3L gas motor. It has 110k Miles on it, 4900 engine hours with 2900 of them idling.
I've been using Kirkland 5w30 with 200hr OCI since new other than the first few OCI.

I've been thinking about going to Mobil 1 0w40 for awhile and today I noticed its on sale for $37CAD per 5L which isn't as good as Kirkland( I stock up when on sale for $40CAD for 2 x 5L) but is still a decent choice.

So, would the Mobil 0w40 be a good choice for my 7.3L gas? It doesn't get worked very hard but does idle a lot as you can see.

Thanks.
If you're in Canada Walmart carries Super tech in 5w40
 
Thanks guys, I picked up 8 jugs of it.

In typical BITOG I have that many jugs of Kirkland still lol.
 
For the OP’s application - which makes more sense : M1 FS 0W40 (SP) or M1 0W30 ESP as both get tossed around for consideration ?
